TAILIEUCHUNG - Lecture Autodesk inventor: CAD viewing and coordinate system commands

Lecture Autodesk inventor: CAD viewing and coordinate system commands. The main contents of the chapter consist of the following: CAD command categories, CAD viewing commands, viewing in AutoCAD, CAD coordinate systems, right hand rule, CAD coordinate system commands. | CAD Viewing and Coordinate System Commands CAD Command Categories Object (draw, modify) View Coordinate System Other categories: Display, inquiry, dimensioning, file management, drawing aids Object is scene being viewed User has control over object, view, CS One model, multiple views CAD Viewing Commands Control position from which an object is viewed Viewer moves, not the object 2D viewing controls Pan Zoom 3D viewing controls Compose pictorial and orthographic views Viewing in AutoCAD PAN Zoom 3DOrbit View Toolbar VPoint VIEW PLAN DView VPORTS CAD Coordinate Systems Governed by the Right Hand Rule Defines a workplane Unique, default global coordinate system Many user-defined, local coordinate systems Right Hand Rule - 1 Thumb indicates the positive x direction Index finger indicates the positive y direction Middle finger indicates the positive z direction Palm of the right hand represents the xy plane Used to define the positive direction of the axes of a three dimensional coordinate system Right Hand Rule - 2 Right thumb aligned with positive axis direction Positive rotation indicated by direction of four fingers curling about axis Variation used to determine direction of positive rotation about an axis Looking down an axis towards origin, positive rotation defined as counterclockwise WorkPlanes 3 mutually perpendicular planes CAD Coordinate System Commands Creates a new, user-defined workplane Used to translate and/or rotate a coordinate system User-defined coordinate system assists in object/feature definition Translate and/or rotate => transform In AutoCAD a closed 2D polyline (profile) can only be extruded perpendicular to the current xy construction plane (., extruded height is in z axis direction) Coordinate Systems in AutoCAD Global coordinate system is called World Coordinate System (WCS) Defines a horizontal xy workplane Top (plan) view is default Local coordinate system is called User Coordinate System (UCS) User defined Coordinate System Control in
